Puddle Flanges: Types and Uses Explained
In piping and waterproofing systems, puddle flanges play a crucial role in protecting structures against seepage, ensuring secure pipe entries, and maintaining system integrity. Whether for water tanks, industrial pipelines, or civil constructions, knowing the right types and specifications can make all the difference. Let’s explore the world of puddle flanges and how Udhhyog brings quality, reliability, and value to every project.
What is a Puddle Flange?
A puddle flange (also sometimes called a “pipe puddle flange”) is a flange or collar fitted around a pipe at its entry point through walls, floors, or tank bases. It helps create a raised barrier or “puddle” zone that prevents water from seeping back along the pipe’s exterior surface. Essentially, it's a sealing and structuring component that assists in waterproofing and protection.
Key Types of Puddle Flanges
GI Puddle Flange: Galvanized Iron flanges, providing corrosion resistance for outdoor or moist environments.
SS Puddle Flange: Stainless steel variants used where higher corrosion resistance or chemical resistance is needed.
MS Hot-Dipped Galvanised Puddle Flanges: Mild steel flanges that are zinc-coated for durability.
Ductile Iron & Cast Iron Puddle Flanges: Stronger, heavier duty options used in industrial or heavy load scenarios.
Rubber Puddle Flange and GRP Puddle Flange: Flexible or composite materials useful in specific waterproofing or chemical environments.
Split Puddle Flanges: Two-part flanges for easier installation around existing pipelines.
Square Puddle Flange: Non-circular forms used where space or orientation constraints exist.
Common Sizes & Connections
Puddle flanges come in a wide array of standard sizes — 32mm, 40mm, 50mm, 65mm, 80mm, 100mm, 110mm, 150mm, and more. The choice depends on pipe diameter, wall or floor thickness, and required waterproofing capacity. Some systems use double flanged pipe with puddle or double puddle flange configurations to enhance sealing or load distribution.
Connection design matters too: manufacturers offer flange spigot with puddle, loose puddle flange types, or integrated designs depending on the installation approach.
Use Cases & Benefits
Water Tanks & Basements: The most common use is at tank walls or slab penetrations, where puddle flange for water tank ensures no leakage into structure.
Industrial and Process Lines: To maintain system integrity in chemical, petrochemical, and wastewater setups.
Fire Water Systems: Puddle flanges in fire water tanks protect against seepage and maintain structural soundness.
Waterproofing Systems: The “use of puddle flange” extends beyond just pipes — in waterproofing design, a well-designed waterproofing puddle flange ties into membranes or coatings to ensure total sealing.

Choosing the Right Puddle Flange: Tips
Match Size Carefully: Always choose flange size that matches your pipe & opening dimensions.
Material Matters: For corrosive or outdoor conditions, go for GI, SS, or ductile iron.
Consider Installation Ease: Split or loose flanges help in retrofit jobs.
Waterproofing Integration: Your flange should support or integrate with your waterproofing membranes or sealants.
Load & Environment Conditions: For heavy structures or variable loads, heavier materials like ductile or cast iron are safer.
